I solve the problem by restarting the software. When I run multiple rendering in a row, after a while the software starts using half the CPU cores, slowing down everything. Because a 2 megapixels image with light and shadows computes for 15 to 20 minutes on my Intel Core i7 2600k.īy the way, I noticed a slight problem in the rendering. Regarding GPGPU, I hope you'll find a way to speed up the rendering. I knew I was familiar with the word "eTeks" but it didn't ring a bell. I bought your book "Les Cahiers du programmeur Swing" years ago when I started my studies. I just realised who you are when I saw your signature. When you see how poor the 2nd rendering is compared to Global Illumination, I wonder if offering an option to activate lights to end users is such a good idea. In this image computed with subpartSizeUnderLight property set to 20 cm, lights added to the home replace default lights in the room where they are placed:Ĭompared to the following Global Illumination rendering, there's still no shadow, no mirror effect, and lights are limited to their room and level: In current version, lights placed in the home have no effect in the 3D view: Meanwhile I might improve light effects in the 3D view as the following images show but I'm not sure this option really worth it. Nevertheless, I recently learnt about shaders and shadow mapping technics and hope to try it sooner or later in Sweet Home 3D since Java 3D supports shaders. Thanks for keeping me aware about progress in graphics card, but don't hope any miracle in the coming versions, because I don't think Global Illumination can be supported easily from Java 3D. Thank you anyway for this incredible free software! It's a shame I can't use my nVidia GTX 570 to do the job! It is build to deal with Global Illumination and Shadows unlike my Intel Core i7 CPU. Regarding the only missing key feature: GPU Computing for rendering, would't it be possible to use the Java lib for OpenCL?Īlso, I remember reading somewhere that Java 8 will natively support OpenCL.ĭo you think this feature could be included in a next realese of your software? Hi, love the software! Really easy to use and very customisable. Using an Intel i7 instead of an i5 really makes the rendering process go twice faster.Įmmanuel Puybaret, Sweet Home 3D developer So as said before, next time prefer to update the number of cores of your processor. Using the CPU and the GPU power are two completely different tasks, even more with from a program written in Java. Would be genius.Miserably I'm not a genius. I was hoping that the GPU would make a difference and the SH3D was optimised to use all hardware. treated myself to a Radeon HD 3890.įire up AMD system monitor and then kicked off a render, CPU maxed out, GPU 0%. Hi all, been out of rendering for a few months due to work.
